Im okay with the combination... keeps our minds open, and makes it so as eldar, he have a glimmer of info on our other races. Sure some of us are going at each other's jugular in the fluff, but we all want the Imperium dead and gone. So the harlequins better get the insinuous plan rolling soon, but they won't, otherwise it would be Rhandra Dhandra(spelling? dont have codex next to me). Not by definition, but when else would they take action?
